The Ethernet Switch built for Compact Tech

Due to stock shortages, the recent version of SwitchBlox cannot perform management or PoE. Read more here.

SwitchBlox is a small ethernet switch with five 10/100MB ports, specifically designed for space-constrained and noisy environments.

With an overall size of 44.5mm (1.75 inches) by 44.5mm (1.75 inches), SwitchBlox is the smallest network switch in the world, making it perfect for robots, drones, or any space-limited networking application.

Plug and play network switch

As an unmanaged network switch, it works straight out the box, all you need to do is...

  1. Apply a 5 to 60V DC supply.
  2. Connect your devices using the included cable set.
  3. It will automatically begin forwarding packets, no coding or setup needed.

Dimensions

We've squeezed all necessary Ethernet circuitry into SwitchBlox without making performance compromises. We use magnetics for improved signal integrity and electrical isolation between each ethernet bus.

Cabling

We use Molex Picoblade connectors on all our boards to keep them tiny. All boards ship with a cable set included, which consists of...

Ethernet Pinout

Below is a handy graphic that shows how we transition from a Molex Picoblade pinout to the standard RJ-45 ethernet cables. For 10/100 Mbps ethernet we use two differential channels, transmit and receive, for a total of four conductors.

Switch Management Features (VLAN, Port Mirroring)

Management features such as VLAN (Port and tag-based) and Port Mirroring is possible on SwitchBlox by using our open-source firmware and software package. To configure this, read our software guide or get in touch for support. 

Passive PoE injection onboard

We’ve added circuitry to SwitchBlox that allows you to inject voltage onto any combination of the ports, simply by toggling a DIP switch on the back.

Enabling this feature requires a 0-ohm resistor to be soldered to the board, more information can be found in the datasheet.
